IMPROVEMENT IN EVAPORATORS.

TO ALL` WHOM- IT` MAY CONGERN:

Be it knownV that I, B. F. CAUFFMAN, of Millerstown, in the county of Perry, and in the State of Pennsyl- Vania, have invented certain new and usefullmprovements in Evaporators; and do hereby declare thatr the following is a full, clear, and exact description thereof, reference ,being had to the` accompanying drawings, and theletters of reference marked thereon. f,

. In the annexeddrawings, making a' part of this specification, A represents the side of a fireplace or furnace, the bottom of which is'mradein the form shown in the drawings, und supported on suitable legs.

The grate of the furnace is adjusted in and forms a part of the bottom thereof at the front end.

- Above Vthe grate, and hinged to one side of the-furnace A, is a. .pan or boiler, F, and situatedjust above and l black' of s aid boiler is another pan, H, whichvI callthe scumming-pan, and which has a pipe, x, leading into the boiler F. Y The boiler F and pan H form the top of the furnace, and thereby secure or obtain all of the heat fromV the furnace. v

Beneath theboiler F, .an,d between'it and the fire-grate, are longitudinal dozuble dampers ce, which are operated by means of suitable handles a a. These dampers are formed by hinging two strips of metal together, `and then hinged o r.pivoted te the sides of the furnace in any convenient manner, and may beuscd to cover the whole fire', or one-Half, as may be required. v

When the said dampers are wholly turned down, another damper, g, placed horizontally across the furnace, is raised, so as to `allow the smoke and heat to pass under the pan H, and out of the flue B.

. Thesedampcrs c d areused to prevent scorching or burning the substance in the boiler`,F, when the same is nearly'empty. l

Another d zimper, in, is placed at the intersection of the furnace and iiue, so'that all draught may be shut o, whenever desired. l I v i 'D represents a small side-furnace, which isattached to the side of the main furnace, as shown, provided with a hole through its top, on which a pan or kettle may be placed, and is a great convenience in finishing up or sugaring oi. v l v i i A track, cl, is adjusted and extendsfrom beneath the grate of the main furnace to the side-furnace D.

E represents a car,l made to run on the track d, and having its bottom slotted or perforated, so as to form a lgrate, and is used to convey coals from the main grate tothe side-furnace.

i A damper, f, is adjusted soins toallow of a draught from the side-furnace into-the` main one, and so as to close the said draught when not required.

The car E is operated ordrawn upthe trackcl by means of a suitable windlass, L, which -is adjusted across the side-furnace D. v

The boiler Fisprovided with a faucet,j, forconvenience in drawing off the substance from it.. i

-The boiler F and pan II are provided ivith movable'lids K K, which are suspended by means of cords ll, and suitable weights. y

- i These lids K K are made with avsteam-pipc, which extends up and works in the steam-pipe L, sofas to carry o allstenin of thejuice orliquid. 4These covers or lids are to bc used'as may be required.

The cords l l pass over suitable pulleys or through loops in or near the top of the building P.

P represents the plan of my building in which I adjust my evaporatingdevicepandis prdvided with a hinged door, r, in one end, and with sliding windows q on each side, and with perforations orv series of hole s s, near the' top thereof, as is fully shown. The perforations s s and sliding windows g q are for the purpose of affording .perfect and complete ventilation. l

I use another small pau, which is not shown, for finishing offlsirup or molasses. i

A4(I 'drst put the juice in the scumming-pan II, and it is then heated, and is then passed through the pipe x, into the boiler F, where it is boiled down to suitable consistency, 'when it is drawn off into asmall pan, not represented, and said pan set into'thev boiler F, which has soulejuice left in it', and the lid K let downyand the Asteam confined s much as convenient, and finish in the boiling-juice, which gives it,'by means of the steam therefrom, the flavor of steamed molasses.

While drawing the juice o' from the boiler, I attach a pipe to the short pipe p, and carry it around, so as to conduct the steam from the pan H between the dampers c c and the boiler F, for the purpose of preventing any burning or scorching of the juice therein, or the boiler. i v v Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The furnace A, provided with double dampers ec and dampers g e m, in combination with a small sidofurnace, D, boiler F, and pan H, and the lids K K, the several partsY being constructed, arranged, and used as and for the purpose specied.

2. The arrangement ofthe track d, car E, and windlass h, with the grate of the larger furnace A, with the side-furnace D, when operated and used as and for the purpose set forth.V

In testimony that I claim the foregoing, I have hereunto set my hand, this day of 1867;

' B.' F. CAUFFMAN.
